                <p class="p_BodyText"><span class="f_BodyText">Behavioral diagrams depict the behavioral features of a system or business process. Behavioral diagrams include the following diagram types:</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Activity Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="activitydiagram.htm">Activity diagrams</a> model the behaviors of a system, and the way in which these behaviors are related in an overall flow of the system.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Use Case Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="usecasediagram.htm">Use Case diagrams</a> capture Use Cases and relationships among Actors and the system; they describes the functional requirements of the system, the manner in which external operators interact at the system boundary, and the response of the system.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">State Machine Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="statediagram.htm">State Machine diagrams</a> illustrate how an element can move between states, classifying its behavior according to transition triggers and constraining guards.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Timing Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="timingdiagram.htm">Timing diagrams</a> define the behavior of different objects within a time-scale, providing a visual representation of objects changing state and interacting over time.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Sequence Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="sequencediagram.htm">Sequence diagrams</a> are structured representations of behavior as a series of sequential steps over time. They are used to depict work flow, message passing and how elements in general cooperate over time to achieve a result.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Communication Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="communicationdiagram.htm">Communication diagrams</a> show the interactions between elements at run-time, visualizing inter-object relationships.</span></p>
<p class="p_SubHeadingL1"><span class="f_SubHeadingL1">Interaction Overview Diagrams</span></p>
<p class="p_BodyText"><span class="f_BodyText"><a href="interactionoverviewdiagram.htm">Interaction Overview diagrams</a> visualize the cooperation between other interaction diagrams (Timing, Sequence, Communication and Interaction Overview diagrams) to illustrate a control flow serving an encompassing purpose.</span></p>
